Alzheimer's Disease Eval, CSF

Sterile Container

2.5 mL (Min 1.5 mLs) CSF Refrigerated

Must be collected in Sarstedt CSF False Bottom Tube 63.614.625 (2.5 mL); also acceptable Sarstedt 72.703.600 (1.5 mL) or Sarstedt 72.694.600 (2 mL). 1. Perform lumbar puncture and discard the first 1 to 2 mL of cerebrospinal fluid (CSF). 2. Collect CSF directly into one of the listed collection tubes until the tube is at least 50% full.* 3. Send CSF specimen in original collection tube. Do not aliquot. Note: Polystyrene collection tubes are not acceptable. Exposure of CSF to polystyrene tubes may result in falsely low Abeta42 concentrations. For more information see Cautions. *The Alzheimer's Association consensus protocol for handling of CSF for clinical measurements of Abeta42 and tau recommends using the drip method for CSF collection and directly collecting into a low-bind polypropylene tube. Although some clinicians prefer the syringe pull method due to speed of collection, the drip method reduces the risk of Abeta42 binding to the plastic of any syringe used.
